v To all whom it mayV concern.'

Be it known that I, GEORGE E. KEMPER, aV citizen of the United States, residing'in the city' of Richmond, Y in the county of Wayne and State of Indiana, have invented a new and useful Furniture-Clamp, of which the following is a full, clear, and comprehensive specification, being such as will` enable others to make and use the same with exactitude.

In the manufacture of cupboards, chiiforobes,

furniture, `such as chiifonniers, and other similar articles, itis imperative, in ordery to accomplish the best results and at the minimum cost, that the assembled parts be securely clamped together in one or in two directions, in order to form close. fitting joints, and

while theparts are thus clamped together,

' device, showing the same in open position.

Fig. 2 is a side elevation of the complete clamp.

*Fig 3 is a top plan view lof. the clamp,

' showing the same in closed or clamping position. Fig. 4v is an end elevation of the complete clamp.Y Q

Fig. 5 isa detail view, taken in sectional elevation. Y

Fig.Y 6 is a perspective view of any one of the several standards or clamping-jaws.

Fig. 7 is a perspective view of the web portion of one of the standards, and Fig. 8 is a detail view showing vparticularly one of the hangers for onefof the shafts. Y

Similar indices denote like parts' throughout the several views. Y A,

In order that the construction, the operation, and the many advantages of -my invention may be fully understood and appreciated I'will nowtake up a detailed description thereof, and will describe the sevcabinets, dressers,l wardrobes,v

eral features as fully and as' comprehensively asImay. y The frame-work of this invention comprises two sets ofsills,l one set being disposed across and resting kon the other set.

The lower set of sills includes six Vinembers which are denoted bynumerals 1, 2, 3, 4, 5, and `6,'the same being arranged in three pairs, the members of each` pair being spaced slightlyv apart. Also the pairs of sillsV are spaced considerable distances apart.

The upper"setof sillsKV includes the six members denoted by the `numerals 7, 8, 9, 10, 11 and 12, thevv same being arranged in three pairs, the members of each pair being spaced a short distance'each apart. Also each pair yof sills are spaced some distance apart.

AA plurality of sub-sills, as thesub-sills 50 and'l, aresecured acrossby bolts ato the undersides of the sills 1, 2, 3, 4, 5 and 6, in

'order to lm'alre lthe frame-work more rigid, vand to provide a support therefor.

All of said sills are formed, preferably, of timber,-and all of theintersecting points are secured* together by a plurality of bolts a, as shown in Figs. 1 and 3. v Y

Numerals 13, 14 and 15 denote longitudinal plungers, which are in the nature of metalbars, which are square in cross section, and which rest across'the members 1,

Y2,3, 4, 5 and 6, and they are located each between'respective pairs of longitudinal sills 7-8, 9-10,` and 11-12.,v v

Inilike manner the cross plungers 16, 17

Aand 18 are located between the respective pairs of sills 1--2, 3-4 and`5v6, and they are also square in ,cross section..

Secured, to and extending down from the underside of the forward endfportions of the sills 1 and 6 are the hangers 19 and 20.

Numeral 21V denotes a relatively large shaft, which is round incross section and it extends between the hangers 19 and'20. v

, Extending out longitudinally from the I ends of the shaft 21 are .the pivots 22 and 23, which are eccentric `,to the shaft 21 with i whichy they are integral. Oneor more apertures 24 are formed through the shaft21 in whichniay be inserted the pins 24', by which said shaft maybe rotatedby hand. -`The pivots 22' and 23 are mounted in the apertures of the respective hangers 1-9 and 20. Y Secured to the undery faces of the forward endV portions of the plungers 16, 17 andy 18 are the respective yokes 25, 26 and 27, each having a vertical slot therein whose width is such asto permit the shaft 21 to-it therein, butl the length of saidv slot is such. as tol permit the shaft to move up and down equal to the eccentricity thereof.

Similar to the above is the cross shaft arrangement: Secured to and extending ,may befrotatedy by hand., The pivots 31 and 32 arevmounted rotatably inthe apertures of the respective hangers 28 andY 29.

Secured to ythe under faces of the lefthand portions of the plungers 13, 14 and 15 are the'respective yokes 34, 35 and36, each having a verticalV slot therein` whose width is such as to permitthe shaft 30 to fit therein, but the length of said slotis such as to permit the shaft to move up and down equal to theeccentricity thereof.

It isy now apparent that the. yokes are mountedy slidably around the respective shaftsV andy that turning the shafts will manifestlyl cause the kplungers to move endwise, reciprocatingbetween the membersl of the respective pairs ofvsills.

- In arranging the device for a certainl size of product to be clamped carey is taken to have. the parts so adjusted that simultaneously. with-the parts being clamped reaching the desired degreeof tightness the eccentrics'lwill reach their maximum clamping eifect, that is to say they will beon dead center thereby, in; addition to their frictional contact, they willcremain inthat position untilthelevers are moved.v in one direction or the other. s

A plurality of. standards` aref' provided, but as they are-all of substantially the same construction a description of one will answer for allrThebaseA and the face-,Bare formed of ka single length or-stri'piof heavy sheeth metal', the; two parts being bent at right-anglesto eachother, the faceB being of considerably greater length than that of the base A. .LettervC denotes the web, which is simplyfa triangular plate fitting thefinner angle ofy thepartsA and B.. Angle-.irons D and E are secured; along on the inner face ofthe member B, and on each side ofthe web C; and.- likewisev angle-irons F and G are; secured alongv on the inner face of the member A on each side of theweb` C. The angle-irons D, and E are; secured toy the web C rivets H, whilev the angle-irons F and G are secured to the web C by the rivets I. The angle-irons F and G are secured to the member A by rivets J, and the angleirons D and E are secured to the member B by the rivets K. Y

Bythe above it is apparent that I form a very strong standard capable of withstanding' great strain.

Certain ofthe standards, formed as set forth, are secured on and extend up from the surfaces of the inner endportions of the sills, that is from the endsof said sills nearestthe shafts 21 and 30. Also removably secured4 on and extending up from the outer end portion of each of the plungers is one of saidstandards, the same being located on the ends of the plungers farthest from the shafts 21V and 30.

It will, now be understood that the device being open, as in Fig. 1, a frame work, such as the assembled material for the body of an article of furniture,` may4 be placed in position on the surfaces of` the upper sills, andL between the various standards. Then by operating the pins 24 and33 the shafts 21 and 30 may be so turned that the standards carried by the plungers willV be moved toward the standards carried by the sills, thereby clampingthe parts of the assembled article of furniture in all directions whereby the-various parts thereof may be permanently secured together by nails or. screws orI otherwise as desired.

- lOther standardsmay be secured either to the sills, as indicated at a: in Fig. 3, or to the plungers, as indicated at a, or both, either for the purpose of spacing shelves or partitions or for adjusting the clamp for various Vsizes of furniture. A

I desire that it be understood that L'various changes may be-made in the several details of: construction from that herein shownk and described, without departing from the spirit cf my invention and without sacrificing any of the advantages thereof.

Having now fully shown and described my invention, what I claim and desire to secure by Letters Patent of the United States, is-

A furniture clamp comprising the combination of a plurality of lower sills arranged in pairs spaced apart, a plurality of upper sills spaced apart andy arranged in pairs at right-anglesto. the lower sills and secured thereto, sub-sills extending across underneath.y the lowery sills and secured thereto, metal bars forming plimgers. located between themembersof eachl pair of the upper sillsand resting slidably on the lower sills, metal bars forming plungers located between the members of each pair of the lower sills andresting slida-blyy on thesub-sills, hangers extending down fromy each` group of sills, shafts extendingacross between each pair of hangers, yokes extending down from the plungers, said shafts being pivoted in said
